Starting in the late 1980’s as small partnership building and renovating homes in the Pioneer Valley, Thayer Street Associates, Inc. has expanded to include not only residential work but commercial projects for retail businesses, offices, educational facilities, restaurants, medical and dental practices, hospitals, hotels, municipal offices, churches, and historical restoration work. TSA has not only grown its general contracting and project management business, but from modest beginnings, has developed a cabinet and millwork shop capable of meeting the requirements of clients and architects to produce casework in quantity and of the highest quality.

Throughout our expansion, we at TSA have strived to maintain a commitment to conduct business with our clients —both residential and commercial— in an open, honest, and personal way. We believe that in all construction projects best results are achieved collaboratively. With this as a goal, we have built a reputation based upon cooperation and positivity which is ultimately beneficial to all involved. To this end, we have developed a network of good relations with architects, engineers, subcontractors, and materials providers to assure excellent communications, efficiency, high quality, good economy, and timely completion of the work.

Please contact us for your next project. Upon request we will provide ample references in the many project types mentioned here whether it is a home, addition, kitchen or bathroom, office remodel, retail store build-out, and more.

You’ll be seeing a lot of us… Get to know us below!
